Climbing High: Ancient Pines and Mountain Peaks of Great Basin
High in the mountains of eastern Nevada, far from noisy cities, sits Great Basin National Park. This park is famous for its dark night skies, deep underground caves, and towering mountain peaks. However, two of its most incredible wonders are found high above the desert floor: the ancient bristlecone pine trees and the icy summit of Wheeler Peak. Exploring this unique wilderness is like taking a step back in time.
As visitors travel up the mountain roads, the warm desert landscape gradually changes. Lower elevations feature sagebrush and pinyon pine forests, but higher up, the air grows cool and thin. Near the treeline, where harsh conditions prevent most plants from growing, lives the Great Basin bristlecone pine. These trees are among the oldest living organisms on Earth. Some of them have been growing for more than 4,000 years! That means they were already saplings when the ancient Egyptian pyramids were being built.
